Just Between Us -- AbFab. Very funny, with the shape, feel, and texture of canon.
Seven Habits of Highly Effective Sex Poodles -- BtVS. Adorable, sweet, makes-me-happy Xander/Anya. I feel like I've seen this title before--like, quite a while ago--but I don't remember reading the story. Also, I could simply be on crack.
Artificial Devotion -- Galaxy Quest.
